Using LrC to create a Time Lapse

Many cameras can create a time lapse movie, .mov. But you can use LrC Slideshow module with this fstoppers article.

Fill the Frame

I got it. Fill the frame, that is important, but it often depends on what the photographers plan.

For me when I am photographing Birds in Flight, BiF. I frequently ask myself, "is that bird to far to get a good photo?"

Yes sensor size and lens focal length figures in to that answer.

So for me my M43 camera and zoom at 300mm, how far away is to far?

My camera has a crop factor of 2x so my equivalent is 600mm. So how far is to far?

Back to PhotoPills FoV Pill. At 300mm, subject 300 ft with FoV of 17'5"x13'. So a large bird say an eagle would "fit". In Postprocessing a 2x crop would lead to  about 8'6"x7'. So basically it fills the frame.  

So maybe set my focus limiter maybe 350' and use the 2x teleconverter I would usually "fill" the frame. But the conventual wisdom is never use your teleconverter. That's true for jpg shooters. But, on my OM-D E-M5 iii, in RAW capture it's only a margination in my view finder. Your camera always captures what is in the sensor. The JPG engine crops you image, RAW doesn't crop. For me when I review the image on the LCD it has a white outline of the 2x crop. Yes if I print a 2x crop image I have 13" on the long edge at 200 pixels per inch. Good enough for an 11x14 inch print.


So when I setup my camera for BiF I'll set my focus limiter to a max of  350 feet minimum of 30 feet, 2x teleconverter. I have configured my camera to have a button to activate/deactivate the teleconverter and another enable/disable focus limiter.  I just have to remember the buttons and functions.
